Electronic Correction Based on Eye Tracking

1. A head mountable display (HMD) system comprising: an eye position detector comprising one or more cameras configured to detect the position of each eye of a user of the HMD; a dominant eye detector configured to detect a dominant eye of the HMD user; and an image generator configured to generate images for display by the HMD in dependence upon the HMD user's eye positions, the image generator being configured to apply a greater weight to the detected position of the dominant eye than to the detected position of the non-dominant eye.

2. An HMD system according to claim 1 , in which the image generator is configured to ignore the detected position of the non-dominant eye.

3. An HMD system according to claim 1 , in which the eye position detector is configured to detect a pupil position of the HMD user's eyes.

4. An HMD system according to claim 1 , in which: the dominant eye detector is configured to detect a degree of disparity of movement of the HMD user's eyes; and the image generator is configured to vary the weighting applied to the detected positions of the HMD user's eyes in dependence upon the detected disparity.

5. An HMD system according to claim 1 in which, in at least a subset of operational modes, the image generator is configured to change the image provided to the non-dominant eye so as to be less prominent than the image provided to the dominant eye.

6. An HMD system according to claim 5 , in which the image generator is configured to reduce one or more of an average luminance, a contrast and a colour saturation of the image provided to the non-dominant eye.

7. An HMD system according to claim 5 , in which the image generator is configured to replace the image provided to the non-dominant eye by a black image.

8. An HMD system according to claim 5 , in which the subset of operational modes comprises a weapons aiming mode in execution of a computer game.

9. An HMD system according to claim 1 , the system comprising an HMD and one or more of a base device and an intermediate device.

10. A method of operation of a head mountable display (HMD) system, the method comprising: detecting, using one or more cameras, a position of each eye of a user of the HMD; detecting a dominant eye of the HMD user; and generating images for display by the HMD in dependence upon the HMD user's eye positions, the image generation applying a greater weight to the detected position of the dominant eye than to the detected position of the non-dominant eye.

11. A non-transitory machine-readable storage medium which stores computer software which, when executed by a computer, causes the computer to carry out the method of claim 10 .
